Title:
ROBOT AUTONOMOUS POSITIONING METHOD BASED ON BRAIN-INSPIRED SPACE CODING MECHANISM AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/184223
Kind Code:
A1
Abstract:
Provided are a robot autonomous positioning method based on a brain-inspired space coding mechanism, an apparatus, a computer device, a storage medium, a computer program product and a robot. The method comprises: acquiring a first image and a second image collected for an environment by a robot during travel (101); according to the first image and the second image, predicting a movement speed of the robot from moment t to moment t+1 (102); according to the t-th map node and the movement speed, creating the (t+1)th map node of a topological map (103); according to respective responses of N position nodes at moment t+1, determining a space code corresponding to the (t+1)th map node (105); and selectively correcting the spatial position represented by the (t+1)th map node on the basis of the space code corresponding to the (t+1)th map node and a database storing a corresponding space code corresponding to at least one previous map node before the (t+1)th map node and the spatial position represented by the at least one previous map node (106).
